How It Works — End-to-End Pipeline

01

Enter Subreddits

Type any public subreddit names separated by commas. Set how many posts per subreddit you want (up to 50). Choose whether to clear old data first.

02

Scrape Reddit Posts

The app hits Reddit's public JSON API to fetch the latest posts. No login or API key needed. Progress is shown live in the Process Log panel.

03

Gemini AI Analysis

Each post's title and content is sent to Google Gemini AI. It returns the sentiment, a summary, and keywords. Rate-limited to 30 req/min on the free tier.

04

View & Filter Results

Analyzed posts appear on the right panel, filterable by All / Positive / Neutral / Negative. Results auto-refresh every 3 seconds as analysis completes.

Platform Features

Reddit Public API Scraping

Fetches posts directly from Reddit's public JSON API — no authentication, no API key, no rate-limit issues on the scraping side.

Google Gemini AI Analysis

Every scraped post is analyzed by Gemini AI for sentiment classification, keyword extraction, and a concise plain-English summary.

100% Private — Browser localStorage

Your data never touches a shared server. Everything is stored in your own browser's localStorage. Completely isolated, even from other users on the same app.

Live Filterable Results

Filter analyzed posts by Positive, Neutral, or Negative sentiment. Results auto-refresh every 3 seconds as new posts finish analysis.

Real-Time Process Logger

Watch every step of the pipeline live — scrape, store, analyze. Each action is logged with timestamps so you know exactly what's happening.
